Hardware requirements
Mini/micro USB cable
EVK-MIMXRT1015 board
Personal Computer
Headphone
Board settings
No special settings are required.
Prepare the Demo
Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Insert the headphones into the headphone jack on EVK-MIMXRT1015 board.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
Note: This demo outputs 215HZ sine wave audio signal. When the demo runs successfully, you can hear the tone and the log would be seen on the OpenSDA terminal like:
SAI functional interrupt example started!
SAI functional interrupt example finished!
Known issue: If pressing SW9 to rerun the demo frequently, it may cause booting from QSPI nor flash failed, since the SA1 RXD0 pin is muxed as boot configurations pin. Workaround: To use SW3 instead of SW9.
Note: To debug in qspiflash, following steps are needed:
Select the flash target and compile.
Set the SW8: 1 off 2 off 3 on 4 off, then power on the board and connect USB cable to J41.
Start debugging in IDE.
Keil: Click “Download (F8)” to program the image to qspiflash first then clicking “Start/Stop Debug Session (Ctrl+F5)” to start debugging.
